I am working with my thesis project which is about mimicking of the human wrist. I used the Kinect for Windows sensor as my controller and also my input data on my micro controller unit. I have noticed that the depth value that I had was to small for me to get the range of the wrist movement along x and y axis. Which result to an inaccurate movement of the robotic wrist because it the range value that I am getting is smaller than the normal angle of motion the human wrist can do.

I just want to ask if is there anything that I could do to make the range of my wrist become bigger than the human wrist can do. So that I could use it to make the robotic wrist's movement more accurate that it could copy the human wrist more likely. I do need your help with this. Thank you!
